Objective:To assess the life quality of the patients with tongue cancer after operation.Methods:80 cases of tongue cancer following surgery during 1994 to 1998 were reviewed with questionaire.Scords of University of Washington Quality o f Life (UW-QOL) were analysed to evaluate their life quality.Results:(1) 3-year survival rate was 72.5%,higher survival rate was observed in the patients with I and II stage lesion than those with Ⅲ and Ⅳ stages.(2) 58 cases of survivers had UW-QOL average score of 618. Some patients had serious disability in mastication, swallowing,speaking and shoulder movement.(3)Patients retaining mandible or with skin flap repair had higher quality of life than the others.Conclusion:Following surgery,tongue cancer patients still maintain comparatively high quality of life.Reconstruction of mandibular or tongue is very importent for the life quality of the patients.

Objective To explore the psychological status of the patients with breast cancer and its influencing factors.Methods The psychological health status in 896 patients with breast cancer and 1 419 patients with benign breast diseases were surveyed and analyzed by adopting the Self-reporting Inventory(SCL-90).At the same time,SCL-90 was also used to analyze the differences of psychological health status among breast cancer patients with different occupations,degrees of education and family support attitudes.Results The each factor scores in breast cancer patients were higher than those in benign breast disease patients(P＜0.05).The scores of obsessive symptoms and somatization factor in breast cancer patients were higher than those of other factors(P＜0.05).In breast cancer patients,the proportion of workers and cadres with obsessive symptoms was higher than that of farmers.The family support attitude was good,and the proportion of obsessive symptoms was lower.The higher the education level,the lower the proportion of somatic symptoms.Conclusion Aiming at the existence of mental problems of higher somatization and obsessive symptoms,conducting the psychological counseling and intervention can improve the quality of life in the patients with breast cancer.

Objective:To establishing model of anterior disc displacement(ADD) of temporomandibular joint(TMJ) by persistent inducement of traction through orbit. Methods:The inferior and posterior walls of orbit of right side in 8 rabbits were exposed. The anterior part of disc was vertically passed through using a suture needle with an elastic rubber. The double strands of the elastic rubber was stretched forward from 7 mm to 16 mm and fixed in the hole drilled in the zygomatic arch bellow inferior orbit. The rabbits were killed 1,2,4 and 8 weeks after operation respectively, then both TMJs of each were resected. The paraffin sections were made and stained with hematoxylin & eosin. Results:The mandible of the rabbits deviated to the left side with inclined attribution of incisors. The disc was displaced forward and the degree of ADD in the rabbits was similar. Conclusions:The disc anterior displacement of temporomandibular joint can be induced by persitent anterior traction of the disc.

Objective To observe the efficacy of No. 1 Baiban granules in the treatment of vitiligo using skin confocal laser scanning microscopy. Methods The study was approved by the hospital ethics committee. Nine-two patients with qi stagnation and blood stasis were collected from Department of Dermatology of the Affiliated Hospital of Tianjin Academy of Traditional Chinese Medicine and were randomly assigned to two groups. The experimental group (n=49) received oral Baiban granuleΙ, 3 g, twice a day, transfer factor capsules 6 mg, 3 times a day, 0.1%mometasone furoate cream (excluding the face) for external use, once a day, or 0.1%tacrolimus ointment (Afacial), twice a day for 3 months. The control group (n=43) only received oral transfer factor capsules 6 mg, 3 times a day, 0.1%mometasone furoate cream (except for the face) for external use, once a day, or 0.1%tacrolimus ointment (face), twice a day, treatment for 3 months. The therapeutic effect was observed in two groups. CLSM was used to monitor the compound color and pigment recovery level, and changes of the number of dendritic cells and inflammatory cell infiltration in skin. Results The compound color was improved significantly after treatment in experimental group and control group. The total effective rate was higher in experimental group than that of control group (81.63% vs. 69.77%,χ2=3.947,P<0.05). Results of CLSM observation showed that the pigment recovery of skin lesion, the proportion of dendritic cells and inflammatory cells were significantly higher in experimental group than those of control group (P < 0.05). Conclusion The treatment effect of No. 1 Baiban granules is more obvious for vitiligo of qi stagnation and blood stasis.

BACKGROUND:The relationship of fibroblast growth factor receptor 3 (FBGFR3) and malignant tumor has been confirmed. However, domestic and foreign studies on whether FBGFR-3 plays a role in odontogenic tumor with special biological characteristic are few.OBJECTIVE: To observe the expression of FBGFR-3 in odontogenic tumor.DESIGN: A randomized controlled observation.SETTING: Department of Stomatology, Medical College, Medical College of Huzhou Teachers College; Stomatology Hospital Affiliated to Zhejiang University.MATERIALS:This experiment was carried out in the Stomatology Hospital, Medical College Affiliated to Zhejiang University between January 2003 and December 2004.All the samples were from the odontogenic tumor patients admitted to Department of Pathology, Stomatology Hospital Affiliated to Medical College of Zhejiang University between year 1999 and year 2000, including 29 patients with ameloblastoma, 20 keratocyst and 36 primordial cyst. Normal dental crypt or residual dental lamina epithelium tissue served as control. All the samples were embedded by paraffin, sliced into 3 to 5 μm-thickness sections, placed on polylysine-spread slide, and dried for later use.METHODS: The expressions of FBGFR-3 in the normal dental crypt or residual dental lamina epithelium tissue,odontogenic ameloblastoma, keratocyst and primordial cyst were detected by immunohistochemical method.MAIN OUTCOME MEASURES: Expressions of FBGFR-3 in ameloblastoma, keratocyst and primordial cyst.RESULTS: The expression of FBGFR-3 in the ameloblastoma, keratocyst and primordial cyst was positive, presenting 59%, 45% and 8%, respectively, and there were significant differences in expression of FBGFR-3 among these three;FGGFR-3 was not expressed in the normal dental crypt and residual dental lamina epithelium tissue. FBGFR-3-positive cells gathered in the maturation region of tumor cells.CONCLUSION: FBGFR-3 may be related to the pathogenesis of ameloblastoma and keratocyst, and terminal differentiation mechanism.

Objective To investigate the effect and significance of early coronary artery bypass grafting (CABG) on the expression level of nerve-related factor at infracted border zone (IBZ) in dogs with acute myocardial infarction (AMI).Methods The anterior descending coronary artery of all thirty dogs randomly assigned into experimental group(n =22) and control group(n =8)were ligated into MI model.The experimental group included those undergoing CABG 1(n =6),2 week(n =4),4 week(n =6)and 6 week (n =6) after MI,and control group(n =2) was established for every experimental group.We detected the local expression level of nerve-related factor such as GAP43 mRNA,NGF mRNA and SYN mRNA at normal myocardium and infracted border zone myocavdium by means of RT-PCR through thoracotomy at eight weeks after surgery.Results Four dogs of every experimental group and all dogs of control group survived to the end of the study.The local expression level of GAP43 mRNA,NGF mRNA and SYN mRNA in control groups was significantly higher than that in normal and experimental groups (P ＜0.01 ).The local expression level of GAP43 mRNA,NGF mRNA and SYN mRNA in 4 and 6 weeks bypass groups was significantly higher than that in normal and 1,2 weeks bypass groups (P ＜0.05).There was no statistically significant the expression level of SYN mRNA among all experimental groups (P ＞ 0.05 ).Conclusions Early CABG surgery for AMI in dogs could lessen the expression level of nerve-related factor and the sympathetic remodelling at IBZ.Especially CABG surgery two weeks after MI could lessen the sympathetic maximacily.
